Document Summary
The upper respiratory system is sometimes called the conducting system to get the air into your body. There are a lot of hollow spaces that connect in the upper respiratory system to allow the passage of air. The pharynx is shared with the digestive system needs to be protected by epiglottis. There are layers of different types of cells that explain the function o. In upper respiratory system, the function is to humidify and warm the air. If you collect too many particles you don"t need you collect mucus and cough it up (you"re sick!) mucus. Eventually smokers lose the cilia completely causing abnormal cells which when divide is causing cancer. You want the pharynx to be protected stratified squamous epithelium. In the larynx you have respiratory mucosa with mucus layer. The rest of the lower respiratory system (different parts of your lungs) are there to conduct the respiration of the body.
